  On the other hand, a building unit in which a frame structure such as a ramen structure is formed by a beam and a column will be bent and deformed into a S-shape when viewed from the side when a horizontal force is applied due to an earthquake. May cause vibration.

  If the vibration of the building can be suppressed by using such bending deformation, it is not necessary to separately provide a device having a large exclusive volume such as a conventional damping wall.

  Therefore, an object of the present invention is to provide a building damping structure that can reduce vibration generated in a building by using bending deformation of a beam material or a column material.

  In order to achieve the above object, a vibration damping structure for a building according to the present invention is a vibration damping structure for a building in which a framework is formed by a beam material and a column material, and at least a part of the beam material or the column material. A long vibration damping plate disposed along the longitudinal direction of the structural deformation portion that undergoes bending deformation when the building receives an external force, and an interval in the longitudinal direction of the vibration damping plate. A connecting portion for connecting the structural deformation portion and the damping plate, and a damping material interposed between the damping plate and the structural deformation portion at at least one of the connection portions. A vibration damping device is provided.

  Here, the building is a unit building configured by adjoining a plurality of building units in which a framework is formed by a beam material and a column material, and between the beam materials of the adjacent building units or the The vibration damping device can be provided between the column members.

  Further, the vibration damping device is arranged continuously over substantially the entire length of the beam material or the column material, and the damping material is interposed on both sides of the beam material or the column material in the longitudinal center. It can be set as the structure by which a connection part is provided.

  Furthermore, the structure which the said damping device of a different body is each arrange | positioned on the both sides of the longitudinal direction center of the said beam material or the said column material may be sufficient.

  Moreover, the structure which provides at least one location of the said connection part in the joint part vicinity of the said column material and the said beam material, and makes the connection part rigid connection may be sufficient.

  Further, the vibration damping device can be disposed on a ceiling beam of the building.

  Furthermore, the vibration damping device may be disposed across the ceiling beam on the lower floor and the floor beam on the upper floor of the building.

  Further, in the connection portion where the damping material is interposed, the damping material can be joined to both side surfaces of the damping plate, and the side surface of the damping material can be fixed to the structural deformation portion.

  Further, in the connecting portion for interposing the damping material, the damping material is joined to both side surfaces of the damping plate, and through holes are formed in the damping plate and the damping material, and bolts are formed in the through holes. It is also possible to fix the both ends of the bolt to the structural deformation portion.

  In addition, in the connection portion where the damping material is interposed, an insertion hole is provided in the damping plate, the damping material formed in a cylindrical shape is inserted into the insertion hole, and a bolt is inserted into the center hole of the damping material. And it is good also as a structure which fixes the both ends of the volt | bolt to the said structural deformation part, respectively.

  The vibration damping structure of the building of the present invention thus configured has a vibration damping device along the longitudinal direction of the structural deformation portion such as a beam member or a column member that undergoes bending deformation when the building receives external force. Be placed. And the damping material is interposed in at least one place of the connection part which connects a structural deformation part and the damping plate of a vibration damping device.

  When the structural deformation portion undergoes bending deformation due to an external force, an amplified displacement difference is generated between the structural deformation portion and the vibration damping plate at the place where the damping material is disposed, and this amplified displacement difference is the damping material. The vibration is attenuated by the amount of operation.

  With such an amplifying mechanism, it is possible to reduce the vibration of the building by utilizing the bending deformation of the beam material and column material generated by the external force.

  Further, if the vibration damping device can be arranged along the beam material or the column material, the vibration damping device becomes an obstacle, and there is almost no restriction in designing such as a floor plan.

  Furthermore, if a vibration damping device is arranged along the longitudinal direction of the beam or column material between adjacent building units, the vacant gap will be effectively used from the beginning. There is almost no restriction on the design such as the floor plan because the vibration damping device becomes an obstacle.

  Furthermore, if the vibration damping device is placed continuously over the entire length of the beam and column material, the accumulated displacement difference due to bending deformation of the beam and column material will increase, effectively reducing the vibration of the building. it can.

  Furthermore, the vibration damping device can be partially arranged at a location where the deformation of the structural deformation portion becomes large. For example, when a beam or a columnar material is deformed into an S shape when viewed from the side, vibration damping of the structural deformation portion can be efficiently performed by arranging vibration damping devices around the antinodes of deformation that appear on both sides of the center in the longitudinal direction. Can be attenuated.

  In addition, if the joint of the vibration damping device in the vicinity of the joint between the column member and the beam member is made to be a rigid joint, the damping plate cantilevered from that position, so that the S-shaped deformation at the tip of the damping plate A large difference can be used, and vibration can be efficiently damped.

  Furthermore, by arranging the vibration damping device on the ceiling beam of the building, the vibration can be attenuated at a high position, and the vibration of the building can be efficiently suppressed.

  Also, by placing the vibration damping device across the upper floor beam and the lower floor beam, the height of the damping plate of the vibration damping device can be increased to increase the bending rigidity. The difference from the deformed structural deformation portion becomes large, and vibration can be effectively damped.

  Further, if the connecting portion is configured to join the damping material to both sides of the damping plate, the connecting portion can be fixed to the structural deformation portion by an adhesive, a tapping screw, or the like, and attachment is easy.

  Furthermore, if it is the structure attached through a volt | bolt, even if it fixes by few places, a vibration damping device can be reliably attached to a structural deformation part.

  And when attaching a damping board via a cylindrical damping material, even if it is a case where the space | interval between beam materials is narrow, a damping material of desired thickness can be interposed between damping boards. Therefore, it is possible to provide a damping structure adjusted to the thickness of the efficient damping material.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic diagram of a unit building 100 as a building for explaining the structure of the building vibration damping structure of the present embodiment.

  First, from the configuration of the unit building 100, the unit building 100 is a building such as a detached house constructed by installing a plurality of building units 1 adjacent to each other as shown in FIG.

  The unit building 100 shown in FIG. 1 has four lower building units 1A,... Installed on the first floor, and four building units 1,.

  As shown in FIG. 2, the building unit 1 (or the lower floor building unit 1 </ b> A) is a column 13 as a column material arranged at four corners, and a beam material spanned between the upper end and the lower end of the column 13. A frame is formed from the ceiling beam 11 and the floor beam 12.

  Here, the pillar 13 can be formed of a square steel pipe, and the ceiling beam 11 and the floor beam 12 can be formed of a C-shaped steel material or the like. Moreover, the ceiling beam 11, the floor beam 12, and the column 13 are rigidly joined by welding or the like, and this frame forms a rectangular box-shaped frame structure.

  And the building units 1 and 1A comprised in this way are arrange | positioned with a clearance gap between beam materials (in FIG. 4, ceiling beams 11 and 11), as shown in FIG.

  In the present embodiment, as shown in FIG. 1, the vibration damping device 2 is arranged between the building units 1, 1 (1A, 1A) arranged adjacent to each other in the horizontal direction. This FIG. 1 arrange | positions the vibration damping device 2 between the ceiling beams 11 and 11 of adjacent building units 1 and 1, respectively, and between the ceiling beams 11 and 11 of adjacent lower floor building units 1A and 1A, and the building of an upper floor A unit building 100 in which the vibration damping device 2 is arranged between the floor beams 12 and 12 of the units 1 and 1 is shown.

  As shown in FIG. 3, the vibration damping device 2 is formed to have substantially the same length as the ceiling beam 11 and is disposed along the longitudinal direction of the ceiling beam 11.

  Here, two curves shown by two-dot chain lines in FIG. 3 are structural deformation portions when a horizontal external force P is applied from the left side of the ceiling beam 11 of the building unit 1 due to, for example, an earthquake or wind. The deformation modes of the S-shaped deformations S1 and S2 as bending deformations occurring in the ceiling beam 11 are schematically shown by increasing the scale of displacement. Although not shown, bending deformation such as the S-shaped deformations S1 and S2 also occurs in the column 13 and the floor beam 12.

  Further, it can be seen from the shapes of the S-shaped deformations S1 and S2 that there is almost no deformation at the center in the longitudinal direction of the ceiling beam 11, and that the maximum deformation portions that swell in an abdomen form on both sides.

  And in order to attenuate the deformation | transformation of this largest deformation | transformation part, as shown in FIG. 3, the attenuation | damping connection part 23 ... as a some connection part is provided at intervals in the longitudinal direction of the vibration damping apparatus 2. As shown in FIG. . Here, it is preferable to provide this attenuation connection part 23 in a maximum deformation part so that the displacement difference by S-shaped deformation | transformation S1, S2 of the ceiling beam 11 can fully be utilized.

  As shown in the sectional view of FIG. 4, the vibration damping device 2 around the damping connection portion 23 includes a damping plate 21 disposed in the center and damping rubbers 22 and 22 as damping materials disposed on both side surfaces thereof. And tapping screws 23a,... For fixing the damping rubbers 22, 22 to the ceiling beams 11, 11, respectively.

  Further, as shown in FIG. 4, the ceiling beam 11 for fixing the vibration damping device 2 has a substantially sectional view C by flanges 11b and 11b arranged in parallel in the vertical direction and a web 11a connecting the ends thereof. It is a steel material formed in a letter shape.

  On the other hand, the damping plate 21 of the vibration damping device 2 is a rectangular steel plate whose height and length are slightly smaller than the web 11 a of the ceiling beam 11. The damping plate 21 is a member having a large bending rigidity that can attenuate the deformation of the ceiling beam 11, and the thickness and the height may be set according to the size and the deformation amount of the ceiling beam 11.

  Further, damping rubbers 22 and 22 are attached to both side surfaces of the damping plate 21 by an adhesive or the like. As the damping rubber 22, a damping rubber material, an asphalt damping material or the like can be used. Further, the damping rubber 22 can be disposed over the entire length of the damping plate 21 or may be disposed only around the damping connection portion 23.

  Further, a protective plate 22a formed of a steel plate, an aluminum plate, a plywood or the like is attached to the side surface of the damping rubber 22 that faces the web 11a of the ceiling beam 11. This protective plate 22a is provided in order to ensure the shear strength against the tapping screw 23a.

  The damping rubber 22 and the ceiling beam 11 thus configured can be joined by a tapping screw 23a. In addition to the tapping screw 23a, it can be fixed with an adhesive alone.

  When the tapping screw 23a is used, a screw hole (not shown) for inserting the tapping screw 23a is provided in advance at a predetermined position of the web 11a of the ceiling beam 11.

  Next, the effect | action of the damping structure of the unit building 100 of this Embodiment is demonstrated.

  The damping structure of the unit building 100 of this embodiment configured as described above is between the beam members of the building units 1 and 1 installed adjacently (between the ceiling beams 11 and 11 and between the floor beams 12 and 12). In addition, the vibration damping device 2 is arranged along the longitudinal direction of the beam material. In the damping connection portion 23, the vibration damping device 2 is fixed to the beam material via the damping rubber 22 with a tapping screw 23 a or the like.

  On the other hand, when the building units 1 and 1 receive a horizontal force (external force) due to an earthquake or the like, the ceiling beams 11 and 11 cause S-shaped deformations S1 and S2. When the ceiling beams 11 and 11 are deformed into S-shapes S1 and S2, the damping rubber 22 around the damping connecting portion 23 of the maximum deforming portion, which is the antinode of deformation, is greatly deformed.

  That is, an amplified displacement difference is generated between the ceiling beams 11, 11 that are structural deformation portions and the damping plate 21, and the amplified displacement difference becomes an operation amount of the damping rubber 22 to attenuate the vibration. .

  As described above, the damping rubber 22 is disposed at a position where deformation is increased, and the damping rubber 22 can be effectively expanded and contracted, thereby effectively attenuating the vibration.

  As a result, the vibration of the unit building 100 composed of the plurality of building units 1,... Can be reduced.

  In addition, if the vibration damping device 2 is originally arranged between the beam members having a gap (between the ceiling beams 11 and 11 and between the floor beams 12 and 12), the wall arranged in the living room space as in the past. The layout design is not constrained like the vibration control structure provided with the device. Furthermore, since the vibration damping device 2 does not protrude into the room or the ceiling behind the beam members, the room space is narrowed or the piping is hindered, and there is almost no restriction during the design.

  Furthermore, if the vibration damping device 2 is arranged continuously over substantially the entire length of the beam members (ceiling beam 11 and floor beam 12), the accumulation of displacement differences due to the S-shaped deformations S1 and S2 of the ceiling beam 11 increases, which is effective. The vibration of the unit building 100 can be attenuated.

  In addition, by arranging the vibration damping device 2 on the ceiling beam 11 of the building unit 1, vibration can be attenuated at a high position, and vibration of the unit building 100 can be efficiently suppressed.

  Further, if the damping connection portion 23 of the vibration damping device 2 is configured to join the damping rubbers 22 and 22 to both sides of the damping plate 21, it can be fixed to the beam material by an adhesive or a tapping screw 23a. Easy to install.

  Hereinafter, Example 1 of a form different from the above-described embodiment will be described. The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  In the above-described embodiment, the case where the vibration damping device 2 having substantially the same length as that of the ceiling beam 11 has been described has been described. However, in Example 1, separate attenuations are provided on both sides of the center of the ceiling beam 11 in the longitudinal direction. A case where the vibration devices 2 and 2 are arranged will be described with reference to FIG.

  That is, in the first embodiment, as shown in FIG. 5, the vibration damping devices 2 and 2 are arranged only in the vicinity of the abdomen of deformation where deformation occurs due to the S-shaped deformations S1 and S2.

  The vibration damping device 2 is provided with pin connection portions 24 and 24 as connection portions near both ends of the ceiling beam 11 which are less deformed by the S-shaped deformations S1 and S2, and in the central portion near the maximum deformation portion. An attenuation connection portion 23 is provided as a connection portion.

  Thus, both ends of the vibration damping device 2 with a small deformation are connected to the ceiling beam 11 without restricting the rotation by using the pin connection portions 24, 24, and the central portion where the deformation between them is large is the attenuation connection portion 23. By doing so, the damping plate 21 rotates at the pin connecting portions 24, 24, and the damping rubber 22 around the damping connecting portion 23 of the maximum deforming portion, which is the antinode of deformation, is greatly deformed.

  That is, the vibration damping device 2 follows the ceiling beam 11 at the pin connection portions 24 and 24, and the relative displacement difference from the attenuation connection portion 23 which is the maximum deformation portion increases, so that the damping rubber 22 operates sufficiently. Thus, vibration is effectively absorbed, and the vibration of the ceiling beam 11 can be attenuated.

  Further, if the vibration damping device 2 and the damping rubber 22 are arranged only at a location where the damping effect of deformation becomes large, the amount of material used can be reduced, and the vibration of the ceiling beam 11 can be efficiently damped. it can.

  Other configurations and operational effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  Hereinafter, a vibration damping device of a form different from the above-described embodiment will be described. The description of the same or equivalent parts as those described in the embodiment or examples will be given with the same reference numerals.

  First, the damping connection portion 33 as the connection portion of the vibration damping device 3 described with reference to FIG. 6 is similar to the vibration damping device 2 of the above-described embodiment, and includes a damping plate 31 formed of a rectangular steel plate. These are mainly composed of damping rubbers 32 and 32 as damping materials joined to both side surfaces thereof, and bolts 33a and nuts 33b as fixing means.

  And in this damping connection part 33, the through-hole 34 larger than the axial diameter of the volt | bolt 33a is formed in the damping board 31, and when the volt | bolt 33a is penetrated, the volt | bolt 33a and the damping board 31 do not contact. It has become.

  The damping rubbers 32, 32 arranged on both sides of the damping plate 31 are also formed with through holes 34 communicating with the holes of the damping plate 31. Further, a protective plate 32a formed of a thin steel plate or the like is attached to the surface of the damping rubber 32 facing the web 11a of the ceiling beam 11, and there is a hole slightly larger than the shaft diameter of the bolt 33a. Is formed.

  Then, when the bolt 33a is inserted into the hole of the protective plate 32a and the through hole 34 from the one ceiling beam 11 side and fastened with the nut 33b on the other ceiling beam 11 side, the vibration damping device 3 is connected to the ceiling beams 11 on both sides. 11 is fixed.

  In addition, when the ceiling beams 11 and 11 are deformed in the state where the vibration damping device 3 is fixed in this way, the deformation is transmitted to the protection plates 32a and 32a via the bolts 33a and is attenuated from the protection plates 32a and 32a. The vibration is transmitted to the damping plate 31 via the rubbers 32 and 32.

  Thus, if it is the structure attached via the volt | bolt 33a, even if it fixes with few places, the vibration damping device 3 can be reliably attached to the ceiling beams 11 and 11.

  Next, a damping connection portion 43 as a connection portion of a vibration damping device 4 of another form described with reference to FIGS. 7 and 8 includes a vibration damping plate 41 formed of a rectangular steel plate, and the vibration damping plate 41. It is mainly comprised from the attenuation | damping cylinder 42 as an attenuation | damping material inserted in the insertion hole 44 provided in this.

  In the damping cylinder 42, a cylindrical inner peripheral plate 42a is attached to the inner peripheral surface of a damping rubber 421 formed in a thick cylindrical shape, and the outer peripheral surface is covered with an outer peripheral plate 42b. The inner peripheral plate 42a and the outer peripheral plate 42b can be manufactured in a cylindrical shape using a steel plate, an aluminum plate, or the like.

  The hole formed by the inner peripheral plate 42 a becomes the center hole 42 c into which the bolt 43 a of the attenuation connection portion 43 is inserted.

  That is, if the vibration damping device 4 is arranged between the ceiling beams 11 and 11, the bolt 43 a is passed from the one ceiling beam 11 side to the center hole 42 c of the attenuation cylinder 42, and the nut 43 b is fastened on the other ceiling beam 11 side. The vibration damping device 4 is fixed to the ceiling beams 11 and 11 at the attenuation connection portion 43.

  Further, when the ceiling beams 11 and 11 are deformed in a state where the vibration damping device 4 is fixed in this way, the deformation is transmitted from the inner peripheral plate 42a to the damping rubber 421 via the bolt 43a, and from the outer peripheral plate 42b. It is transmitted to the damping plate 41.

  That is, since the thickness of the damping rubber 421 is the amount of the damping material interposed between the damping connection portion 43 and the damping plate 41, even when the gap between the ceiling beams 11 and 11 is narrow, The thickness of the damping material can be adjusted to a desired thickness.

  That is, since the deformation of the ceiling beams 11 and 11 is transmitted to the damping plate 41 via the damping rubber 421, the damping effect of the deformation of the ceiling beams 11 and 11 varies depending on the thickness of the damping rubber 421. .

  On the other hand, when the damping effect is to be adjusted by adjusting the thickness of the damping rubber 421, in the configuration in which the damping rubbers 22 and 22 are arranged on both sides of the damping plate 21 as in the above embodiment, Although the thickness of the damping rubbers 22 and 22 is limited by the width of the gap between the ceiling beams 11 and 11, with the configuration like the damping cylinder 42, the width of the gap between the ceiling beams 11 and 11 is large. The thickness of the damping rubber 421 can be adjusted without limitation.

  Other configurations and functions and effects are substantially the same as those of the above-described embodiment or other examples, and thus description thereof is omitted.

  Hereinafter, a vibration damping device of a form different from the above-described embodiment will be described. The description of the same or equivalent parts as those described in the embodiment or examples will be given with the same reference numerals.

  In the third embodiment, a cantilever type in which one end of the vibration damping device 5 is rigidly joined without interposing a damping material will be described with reference to FIGS.

  As shown in FIG. 9, in the vibration damping device 5, one end of the building unit 1 on the column 13 side is a rigid joint portion 54 as a connection portion, and the other end is interposed with a damping rubber 52 as a damping material. Attenuating connection portion 53 as a connecting portion.

  As shown in detail in the cross-sectional view of FIG. 10, the rigid joint 54 of the vibration damping device 5 has spacers 54 c and 54 c interposed between the damping plate 51 and the webs 11 a and 11 a of the ceiling beams 11 and 11. Thus, the damping plate 51 is firmly fixed to the ceiling beams 11 and 11 by bolts 54a and nuts 54b. Here, the form of the spacer 54c is not limited to the one arranged for each bolt 54a, and may be a plate-like one arranged over the upper and lower bolts 54a, 54a. Further, a joint piece used when the ceiling beam 11 is joined to the column 13 may be used in place of the spacer 54c.

  As described above, when one end of the vibration damping device 5 is the rigid joint portion 54, the rigid joint portion 54 moves with the displacement of the ceiling beam 11. On the other hand, the ceiling beam 11 is greatly deformed at the position of the damping connection portion 53. However, since the damping rubber 52 is interposed in the damping connection portion 53, the damping rubber 52 is deformed to absorb the vibration of the ceiling beam 11. Can do.

  Thus, the relative displacement difference between the end portions of the vibration damping device 5 can be increased by using one end as a rigid joint and the other end as a damping connection portion 53 with a damping rubber 52 interposed therebetween. The vibration damping device 5 cantilevered and the vibration of the ceiling beam 11 can be effectively damped.

  Next, with reference to FIG. 11, a description will be given of the vibration damping device 5 </ b> A disposed across the upper floor building unit 1 and the lower floor building unit 1 </ b> A.

  This vibration damping device 5 </ b> A has the same configuration as the above-mentioned cantilever type vibration damping device 5, and the end on the column 13 side is a rigid joint 54.

  Further, the damping plate 51 constituting the vibration damping device 5A is formed at a height that is slightly lower than the combined height of the floor beam 12 of the building unit 1 and the height of the ceiling beam 11 of the lower floor building unit 1A. Yes.

  In the rigid joint 54, one bolt 54 a is disposed on the floor beam 12 and two bolts 54 a and 54 a are disposed on the ceiling beam 11. Rigidly joined across the ceiling beam 11.

  In this way, by arranging the vibration damping device 5A across the floor beam 12 on the upper floor and the ceiling beam 11 on the lower floor, the height of the damping plate 51 of the vibration damping device 5A is increased and the bending rigidity is increased. Therefore, vibration can be effectively damped.

  Other configurations and functions and effects are substantially the same as those of the above-described embodiment or other examples, and thus description thereof is omitted.

  Hereinafter, a vibration damping device 6 different from the above-described embodiment will be described with reference to FIGS. The description of the same or equivalent parts as those described in the embodiment or examples will be given with the same reference numerals.

  Further, the vibration damping device 6 is mainly composed of damping plates 61 and 61 disposed on both sides of the web 111a, and a damping connection portion 63 and a rigid joint portion 64 as connection portions.

  As shown in FIG. 12, the damping plate 61 has a rectangular shape that has a high height near the rigid coupling portion 64 on the joint portion side between the column 13 and the ceiling beam 111 and tapers toward the damping connection portion 63. It is molded into a shape that combines trapezoids.

  Further, in the damping connection portion 63, as shown in FIG. 13A, the damping rubber 62 is fixed to the web 111a of the ceiling beam 111 via the protection plate 62a and the screw 62b, and the damping plate 61 and the protection plate 62a and the damping rubber 62 are joined with an adhesive.

  Further, in the rigid joint portion 64, as shown in FIG. 13B, the damping plate 61 is fixed to the web 111a with bolts 64a and nuts 64b via spacers 64c.

  Here, although the damping plate 61 is illustrated with a constant thickness, the present invention is not limited to this, and the damping connection portion 63 is made thin and the rigid joint portion 64 is made thick. You can also.

  If the vibration damping plates 61 and 61 are arranged on both sides of the web 111a of the ceiling beam 111 composed of the H-shaped steel material in this way to constitute the vibration damping device 6, it becomes possible to mount the building unit. Installation can be done at the factory.

  Moreover, if it attaches to the web 111a in this way, it is possible to easily install the vibration damping device 6 in a building having a framework structure other than the building unit 1.

  Furthermore, even if it is the ceiling beam 11 comprised by C-shaped steel materials as shown in FIG. 4, the vibration damping apparatus 6 can be attached to the web 11a similarly to the fourth embodiment.

  Further, the vibration damping plate 61 of the vibration damping device 6 is not limited to the configuration that is attached to both sides of the webs 11a and 111a of the ceiling beams 11 and 111, and may be only one of them.

  Other configurations and functions and effects are substantially the same as those of the above-described embodiment or other examples, and thus description thereof is omitted.

  The best embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment and example, and the design does not depart from the gist of the present invention. Such modifications are included in the present invention.

  For example, in the embodiment and Examples 1, 2, and 4, the vibration damping devices 2, 3, 4, and 6 mainly disposed on the ceiling beams 11 and 111 have been described. However, the present invention is not limited to this. It can also be arranged on the floor beam 12 or can be arranged across the floor beam 12 on the upper floor and the ceiling beam 11 on the lower floor as in the third embodiment.
